Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted antennas, in particular to a transparent antenna for a car windshield. Background Art

[0002] Car antennas are also called vehicle-mounted antennas. Generally, the antennas on cars are used for the car's radio and radio station. They can be divided into built-in car antennas and external antennas, but other antennas are also installed on cars according to different uses.

[0003] A Chinese patent discloses a transparent automobile windshield antenna (authorization announcement number CN219496344U). This patented technology can solve the problem that when the antenna is installed on the front windshield, it will block the driver's line of sight, so the antenna is usually installed on the rear windshield; but the antenna's ability to receive signals is not as good as when it is installed on the front windshield.

[0004] However, when the existing external transparent antenna is used for a long time, dust easily accumulates on the transparent part, resulting in poor signal reception. The lack of dustproof and waterproof protection structure reduces its service life. Summary of the invention

[0005] In order to solve the above technical problems, the utility model provides a transparent antenna for a car windshield, comprising a glass body and an antenna gold finger, wherein the antenna gold finger is installed on the upper end surface of the glass body, the upper surface of the glass body is a conductive layer, the bottom of the glass body is a smooth layer, a glass cavity is installed on the rear end surface of the glass body, a first slider is installed in the glass cavity by means of sliding fit, a top plate is installed on the upper end surface of the first slider through a connecting seat, and bristles are installed on the bottom of the top plate.

[0006] Preferably: a shaped frame is installed on the front end surface of the glass body, a plurality of temperature sensors are installed on the inner end of the shaped frame, and an antenna gold finger is arranged on the inner end of the temperature sensor.

[0007] Preferably: a fixing groove is provided on the right end surface of the top plate, a fixing roller is rotatably mounted on the front end surface of the fixing groove through a bearing, and a waterproof cloth is wrapped around the outer side wall of the fixing roller.

[0008] Preferably: a glass seat is installed on the right end surface of the glass body, a clamping groove is opened on the upper end surface of the glass seat, and a first clamping head is installed on the bottom of the waterproof cloth.

[0009] Preferably, an upper plate is rotatably mounted on the upper end surface of the top plate via a bearing, and a plurality of first spring rods are mounted on the bottom of the upper plate from front to back.

[0010] Preferably, the left end surface of the first sliding block is clamped with the left end surface in the glass cavity via a second clamping head.

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model adopts a top plate and a brush structure to drive the brush to move, so that the brush cleans the surface of the glass body to avoid long-term dust adhesion on the surface, resulting in poor communication effect.

[0013] 2. The utility model adopts a fixed roller and waterproof cloth structure. When the car is stationary, the waterproof cloth covers and protects the glass body, playing a certain waterproof and dustproof role. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5In this embodiment, a transparent antenna for automobile windshield is provided, including a glass body 1 and an antenna gold finger 2, wherein the antenna gold finger 2 is installed on the upper end surface of the glass body 1, the upper surface of the glass body 1 is a conductive layer 11, the bottom of the glass body 1 is a smooth layer, a glass cavity 12 is installed on the rear end surface of the glass body 1, a first slider 13 is installed in the glass cavity 12 by sliding cooperation, a top plate 14 is installed on the upper end surface of the first slider 13 through a connecting seat, and bristles are installed on the bottom of the top plate 14. When working, the glass body 1 is installed on the lower left side of the windshield, the conductive layer 11 is a highly light-transmitting conductive film, and the resistance value is 15 to 19 ohms, the antenna gold finger 2 is pasted on the glass body 1 for conduction, and the top plate 14 is arranged obliquely above the car body, so it will not block the sight of the windshield, and the top plate 14 is pulled to drive the bristles to move, so that the bristles clean the surface of the glass body 1 to avoid long-term dust adhesion on the surface and poor communication effect.

[0022] A profile frame 15 is installed on the front end face of the glass body 1, and a plurality of temperature sensors 16 are installed on the inner end of the profile frame 15. The inner end of the temperature sensor 16 is arranged with an antenna gold finger 2. When working, the temperature sensor 16 senses the side wall temperature of the antenna gold finger 2.

[0023] A fixing groove is provided on the right end face of the top plate 14, and a fixing roller 17 is rotatably installed on the front end face of the fixing groove through a bearing. A waterproof cloth 18 is wrapped around the outer wall of the fixing roller 17. When working, when it rains, the waterproof cloth 18 is pulled, the fixing roller 17 rotates, and the waterproof cloth 18 covers and protects the surface of the glass body 1. When the car is stationary, the waterproof cloth 18 plays a certain role in dustproof protection.

[0024] A glass seat 19 is installed on the right end face of the glass body 1, and a card slot 25 is opened on the upper end face of the glass seat 19.
